WebIntroduction. The Random Access Channel (RACH) is an uplink transmission used by the User Equipment (UE) to initiate synchronization with the eNodeB. TS36.104, Section 8.3.4.1 [ 1 ] defines the probability of Physical Random Access Channel (PRACH) detection must be greater than or equal to 99% at an SNR of -8.0 dB. WebUplink power control. Uplink power control determines the power for PUSCH, PUCCH, SRS, and PRACH transmissions. It reduces intra-cell and inter-cell interference, as well as the UE power consumpition. Power control is based on pathloss. A UE maintains at most 4 pathloss estimates per serving cell for all PUSCH/PUCCH/SRS transmissions. PCMAX is ... WebJul 1, 2024 · LTE-A systems. It is through the PRACH channel that the user equipment (UE), based on eNodeB’s timing estimates, aligns its uplink transmissions to the eNodeB’s uplink and gain access to the network. One of the initial operations executed by the PRACH receiver at eNodeB side is the translation of the PRACH signal back to base band, i:e:, buy here pay here kansas city mo
